Moral

All middle-aged gentlemen let me advise, If you're married, and hav'n't got very good eyes, Don't go poking about after blue-bottle flies. If you've spectacles, don't have a tortoise-shell rim, And don't go near the water—unless you can swim. Married ladies, especially such as are fair, Tall and slim, I would next recommend to beware, How, on losing one spouse, they give way to despair, But let them reflect, there are fish, and no doubt on't, As good in the river, as ever came out on't.
